Nuland said during a visit to a Ukrainian border guard base outside Kyiv that the United States would provide an additional $10 million in protective gear and nonlethal equipment to Ukrainian servicemen.

Nuland said Ukrainian authorities have devised a plan to regain control over parts of Ukraine's eastern border with Russia but she did not provide details.

Ukrainian President Petro Poroshenko has complained that the inability to properly control that border has made it possible for people to cross into Ukraine from Russia and join pro-Russian separatist forces in the Donetsk and Luhansk regions.
